DARWIN S. WRIGHT, OF MACON, GEORGIA.

MECHANICAL FAN.

SPECIFICATION forming part of Letters Patent No. 267,636, dated November14:, 1882, Y Application filed August 14, 1882. (N0 model.) I

useful Improvement in Mechanical Fans, of

which the following is a full, clear, and exact description, referencebeing had to the annexed drawings, forming part of this specification.

This invention relates to devices for communicating power to a fan, or anumber of fans, for thepurpose of cooling the atmosphere in houses; andthe invention has for its object to provide a construction which shallbe variously adjustable, in order that the fans may be arranged indifferent positions, according to convenience; and the invention furtherprovides means for the convenient use of fans having tubular stems, suchas Japanese fans, which are preferred on account of their lightness.

In the drawings, Figure l is a perspective view, showing the applicationof my invention to use; and Fig. 2 is a detail view.

A represents a crane, which is formed of a bent tube, or of a rod havinga tubular end,

and supported in position by means of a bracket, B, upon which its lowerend rests, and screw-eyes G O, in which the crane is adapted to turn.The tubular upper end of the crane is provided with set-screws c c forholding the extension-rod D, which is inserted into said tubular end,and this rod is provided with a sleeve, E, having a set-screw forholding the vertically-adjustable rod F, to which the fans areconnected. The lower end of the rod F is provided with a bracket, G, inwhich is journaled the spindle H, having a pulley, I, secured to itsupper end, and a hub, J, provided with radial arms K, secured to itslower end. On the arms J, which are cylindrical in form, are placed thetubular stems of the fans L. With this construction the fans may beraised or lowered by the adjustment of the rod F, or moved horizontallyby the adjustment of the fans are to be changed from their propellerlikearrangement, which is used when they rotate horizontally, to a positionin which they shall coincide with corresponding radial planes. By alower adjustment of the crane, however, the propeller-like arrangementof the fans may be used to advantage when the fans rotate in a verticalplane.

In fan attachments for sewing-machines, &c., where the position of theperson to be fanned is a constant one, a variety of adjustments isunimportant; but in a fan for general use-such as mine-w here the poweris to bederived from various sourcessuch as the waterworks of a city,steam attachments, &c.-it is necessary to the practical application ofsuch a fan that it shall be capable of operating in various positions,as convenience may require.

Havingthus described my invention, what I claim, and desire to secure byLetters Patent, 1s-- The combination of the tubular crane, theextension-rod arranged in the tubular crane, and having a sleeveprovided with a thumbscrew, the vertical rod arranged in said sleeve andhaving a bracket for supporting a spindle and pulley, and the hub havingradial arms for receiving the fans, substantially as shown anddescribed, whereby the fans may be.

adapted to rotate either in a horizontal or a vertical plane, as setforth.
